DEGRADABLE FISHING LINES AND NETS
The disclosure provides embodiments of environmentally acceptable fishing lines or fishing nets. Embodiments of the disclosed fishing line or net may comprise a degradable polymer having components derived from i) biomass sources, ii) protein, fatty acid or lipid sources, iii) microbial-based monomers and polymers, iv) agro-based monomers and polymers, v) sugar or starch based monomers and polymers, or combinations thereof, as well as fishing lines and net that further comprise an additive having components derived from i) polyol sources, ii) citrate sources, iii) fatty acid sources, iv) biomass oil sources, or combinations thereof. Some of the embodiments of the disclosed fishing lines or nets may have a suitable fiber core, while other embodiments of the disclosed fishing lines or nets are degradable over a predetermined period of time. The disclosed embodiments are preferred because of the low environmental impact of the disclosed fishing lines or nets when compared to, for example, well known synthetic polymer fishing lines or nets.
TWO-LAYER MULTI-STRAND CABLE HAVING AN IMPROVED SURFACE ENERGY-TO-BREAK
A multi-strand cord (50) comprises an internal layer (CI) made up of K=1 internal strand (TI) having two layers (C1, C3), with the internal layer (C1) being made up of Q internal metallic threads (F1) and the external layer (C3) being made up of N external metallic threads (F3), and an external layer (CE) made up of L>1 external strands (TE) having two layers (C1′, C3′) wound around the internal layer (CI), with the internal layer (C1′) being made up of Q′ internal metallic threads (F1′) and the external layer (C3′) being made up of N′ external metallic threads (F3′). The cord (50) has an energy-to-break per unit area ES≥145 N.Math.mm.sup.−1 with ES=Σ.sub.i=1.sup.NcF.sub.mi×Σ.sub.i=1.sup.NcA.sub.ti/Nc×Cfrag/D where Σ.sub.i=1.sup.NcF.sub.mi is the sum of the forces at break, Σ.sub.i=1.sup.NcA.sub.ti is the sum of the total elongation, Cfrag is the coefficient of weakening, and D is the diameter.
